Abstract

Provided is an image reading device includes a document transport device that sequentially transports a plurality of documents one by one, and the image reading device sequentially reads the plurality of documents transported by the document transport device one by one. The image reading device includes a document discharge tray, a document discharge detector that detects whether or not a document of the plurality of documents is discharged to the document discharge tray, a notifier that notifies that the document of the plurality of documents discharged to the document discharge tray is forgotten to take, and a controller that activates the notifier if it is determined that a last document among the plurality of documents is read and the document discharge detector detects that the document of the plurality of documents is discharged to the document discharge tray.

First claim

What is claimed is:

1. An image reading device comprising a document transport device that sequentially transports a plurality of documents one by one, the image reading device sequentially reading the plurality of documents transported by the document transport device one by one, the image reading device comprising:
a document discharge tray,
a document discharge detector that detects whether or not a document of the plurality of documents is discharged to the document discharge tray;
a notifier that notifies that the document of the plurality of documents discharged to the document discharge tray is forgotten to take; and
a controller that activates the notifier if it is determined that a last document among the plurality of documents is read and the document discharge detector detects that the document of the plurality of documents is discharged to the document discharge tray, wherein
after a job is completed, if a next job is started while the notifier is activated, the controller ends the activation of the notifier.

2. The image reading device according to claim 1 , further comprising:
a large-quantity-document reading function that reads the plurality of documents in a plurality of reading operations during one job, wherein
if executing the large-quantity-document reading function, the controller determines that a last document that is read last in a last reading operation among the plurality of reading operations, is read.

3. The image reading device according to claim 1 , wherein
the controller determines that the last document among the plurality of documents is read.

4. The image reading device according to claim 1 , further comprising:
a display; and
a preview function that displays, on the display prior to execution of a job, an image corresponding to image data obtained by reading a document of the plurality of documents, wherein
if executing the preview function, the controller activates the notifier when an execution key for the job is turned on.

5. The image reading device according to claim 1 , wherein
the controller activates the notifier when a cancel key is turned on during reading of a document of the plurality of documents.

6. The image reading device according to claim 1 , further comprising:
a document platen on which a document of the plurality of documents is set; and
a set-document reading function that reads a document set on the document platen, wherein
after the job is completed, if the controller executes the set-document reading function while the notifier is activated, the controller maintains the activation of the notifier.

7. An image forming apparatus comprising the image reading device according to claim 1 .

8. An image reading device comprising a document transport device that sequentially transports a plurality of documents one by one, the image reading device sequentially reading the plurality of documents transported by the document transport device one by one, the image reading device comprising:
a document discharge tray;
a document discharge detector that detects whether or not a document of the plurality of documents is discharged to the document discharge tray;
a notifier that notifies that the document of the plurality of documents discharged to the document discharge tray is forgotten to take;
a controller that activates the notifier if it is determined that a last document among the plurality of documents is read and the document discharge detector detects that the document of the plurality of documents is discharged to the document discharge tray;
a document platen on which a document of the plurality of documents is set; and
a set-document reading function that reads a document set on the document platen, wherein
after a job is completed, if the controller executes the set-document reading function while the notifier is activated, the controller maintains the activation of the notifier.

9. The image reading device according to claim 8 , further comprising:
a large-quantity-document reading function that reads the plurality of documents in a plurality of reading operations during one job, wherein
if executing the large-quantity-document reading function, the controller determines that a last document that is read last in a last reading operation among the plurality of reading operations, is read.

10. The image reading device according to claim 8 , wherein
the controller determines that the last document among the plurality of documents is read.

11. The image reading device according to claim 8 , further comprising:
a display; and
a preview function that displays, on the display prior to execution of a job, an image corresponding to image data obtained by reading a document of the plurality of documents, wherein
if executing the preview function, the controller activates the notifier when an execution key for the job is turned on.

12. The image reading device according to claim 8 , wherein
the controller activates the notifier when a cancel key is turned on during reading of a document of the plurality of documents.

13. An image forming apparatus comprising the image reading device according to claim 8 .
